script1.py
import sys,time
def main():
t=0
while t!=5:
t =t+1
print t
# Start process
if __name__ == '__main__':
main()
The value of t is getting stored in the 'chunk' variable and through console.log() I am able to see the value of t on the console. I want to display these values on the upload.html page. How do I do this? I tried using res.render and res.write function but nothing got displayed. Any way to do this?
